When the author of X that has two fields x and y wants to serialize it into _any_ archive, he just "says" save(x) and save(y) to the archive.
However, the author of Y that contains an array currently can't just say save_array(a) to the archive, because save_array is not part of the current vocabulary. He needs to say save(a[0]), save(a[1]), ..., save(a[n-1]).
he needs to say save(a) that is ar << a. In any of the proposals the correct override will be invoked.
This only works for C-style arrays with the size fixed at compile time. Think about how one would write "save" for the following: template<class T> struct my_array { T * data_; unsigned size_; };
